What is positive testing in relation to chemistry?

For example, the sentence reads "Sample solutions are
solutions known to contain one of each of the following
ions, silver ion, Ag+(aq), barium ion, Ba2+(aq), and iron
(III) ion, Fe3+(aq). Testing solutions are the solutions
containing a polyatomic ion that can react with one of the
metal ions to give a positive test."

I am then asked to define what a "positive test" is.

I am currently a student who is pretty new to chemistry,
please try and make your answer as simply as possible.

Thanks for the help.
